Abstract
An improved broth medium was developed for high growth yields of
Bacillus subtilis
var.
niger
NCIB 8649,
Bacillus cereus
NCIB 9373, and
Bacillus stearothermophilus
NCIB 8919 and ATCC 7953. Sporulation was abundant (1.1 × 10
8
B. subtilis
var.
niger
and 9.2 × 10
7
B. cereus
per ml) at an initial pH of 7.0. Sporulation of both strains of
B. stearothermophilus
took place (1.9 × 10
7
and 2.4 × 10
7
/ml, respectively) in this medium when initial pH values of 7.7 to 8.7 were used.
